The theme this week on Gizmodo was “survival”—how to survive a natural (or unnatural) disaster, the wilderness, the apocalypse, what have you — including, of course, Apple’s new mobile OS. Here are the highlights from this week.

It may have come to your attention that there’s a fresh version of iOS in town. But aside from a font change, what’s different about this new edition of Apple’s mobile OS? To help you navigate around iOS 9, we’ve listed all the tricks that it can do that were beyond the capabilities of iOS 8.

Ronald Reagan is known as the movie junkie president. He was, after all, an actor before getting into politics. But do you know who watched even more movies than Reagan while in office? Jimmy Carter. And Carter only served a single term.

The OnHub is Google’s latest weird experiment. It’s a $200 router stuffed with fourteen antennas that’s being marketed as a cure-all for people who have a zillion wireless devices with different network needs. But what does that actually mean? I tore down my OnHub with the hardware hackers at iFixit to find out.

In another depressing display of scientific illiteracy, several Republican candidates decided to take jabs at vaccines last night, including Ben Carson–you know, the guy with an actual medical license.

Every product Amazon makes is designed to sell you something else. It’s an open secret. That’s why the company could lose money on the Kindle Fire—yet still reap a profit. Now, Amazon is introducing the most irresistable moneysuck yet: a $50 tablet.

“It’s a machine out of its time, in a way. And a lot of us aren’t quite ready for it yet.” Those were our final thoughts on the Microsoft’s Surface Pro way back in early 2013—an impressive machine, but one that was too much future at the time. Well, the future is now, apparently.

Last year’s hugely popular “ice bucket challenge” saw celebrities pouring buckets of ice water over their heads to help fight Lou Gehrig’s Disease (ALS). Skeptics dismissed it as mere “slacktivism,” but researchers told us that the money led directly to a scientific breakthrough. Can slacktivism actually work?

When a United Airlines flight made an emergency landing this summer due to medical situations on board, as the oxygen masks fell down, some passengers’ phone cameras went up. But psychologists say the instinct to snap a selfie in a near-death experience isn’t all narcissism—it’s also about survival and self-preservation.

It wasn’t the sound that was so shocking. It was the air itself that hit me as I stood mere feet from the polycarbonate resin wall that separated people from the 220-pound remotely controlled battling robots inside the combat arena.

A couple months ago a friend of mine approached me with something that sounded insane. Did I want to kayak from Cuba to Florida? I hadn’t paddled in a year, it was just a month away, and I’d just broken a rib. It was almost certainly a very, very stupid idea. So I said yes.

Hackers, a 1995 movie starring Angelina Jolie’s haircut, hit theaters exactly two decades ago. Its themes have never been more relevant or concerning to our connected society. Can you remember them? I almost can.
